It has been a while since I announced here that the boost::histogram library is nearing completion. And now it happened, Boost-1.70 was released on April 12th, 2019, with boost::histogram.

boost::histogram is a powerful library to make histograms, profiles, and more. boost::histogram was designed to be useful for the beginner and expert alike. It is very customizable, but the defaults are set so that it is safe, fast, memory-efficient for people who just want to get work done. The design is similar to RHist, but offers even more flexibility. It can replace TH1, TH2, TH3, THn, THnSparse, TProfile, TProfile2D, TProfile3D. In the future, it could also replace TProfile2Poly.
A Python frontend is currently developed by Henry Schreiner and myself, an alpha version can be accessed here.
